The car can detect the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for car thieves with no experience to wire a vehicle and then start it. The chip and the key are connected via the circuit board which includes an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder.
